'Be it known that I, HIRAM W. MAPES, Jr`.,of Ripon, in the county-of Fond du Lac, and Stute of Wisconsin, Vhave invented u newztnd improved Spring-Sent for Vehicles; und I do hereby declare that the following is a.

lfull, clear, und exact description thereof, reference being had to the accompanying drawings, making n part of this specilication, in which-f Figure 1 is a. front view ot' the spring-scot. Figure 2 is a. view of one end of the same Figui-e 3 is e. bottom view. Figure is a perspective View of' u portion ot' one of the spring-boards. 4Similar letters of reference indicate corresponding parts lin the several -igures- This invention relates toan improvement onspring-seats for all varieties of vehicles, und for other purposes where v. spring-seet muy be required. It consists in mountin" the seat upon two inclined bonrds,vwhich incline from the centre towardV the endsl orn the sent, 'und whiph are connected nt their upper ends tothe bottom of the seat, by meansA of India-rubber bands, in such manner that ziny load upon the seat will be supported by-s'aid bands and by the inclined boards, thus aording a. comfortable spring-seat, as will be hereinafter described.

Toenable others skilled inthe art to understand my invention, I will describe its construction and operaton.

v In the accompanying drawings, A represents the seatof a. wagon, which may be made in the usual rranner and of any desired ferm.' 'B B are twoincincd" beards, which may be matie n's' wide es tire seat, und whichcare provided with battons, a a, on their lower sides and neer their outer ends, for keeping the seetin pince between the sides of :L jvagonor other vehicle. The inner ends of the two boards B B are notched sons to form inter-` locking tongues, b, which prevent lateral -displacement of the inner endsot' said bonrds'as these ends vibrate I up und down.` These tongues also serve forreceiving the-Iudin-rubberioops'c c, which are connected to staples that are j'driven into the'centrol cross-piece A', of the sean-cs shown injgs. 1 und 4. Strong iron brackets, l) D, :ire secured to the bottom ofthe seat A, transversely across the Is v central piece'A, and on the front and rear ends of thesebrackets gudgeons oryfpivots, ee, are formed which enter bearing blocks ff, that are secured rigidly to the two boards B B', us Ashown in thedruwings. The brackets DD may-be made lightund strong, and they should be secured rmly tolthe bottom of the seat. The weight of the seat is'supported upon the two boardsB B uniformly, and at points which are between the'extremities of saidboards. The` inner or interlocking ends of the sprin -boards B B are held up against the crosspiece A when; there is no weight upon the seat A,but when thereis u..weight upon thel-seat the spring loops.

The upper ends of the springboards B Bnre connected together by means of pins, g, which are formed on plates' that are secured to the front und rear edges'of thc-se bonrds,'which pins projectl through oblong slots thst are-mode throughA the end: of plates y', as shown in figs. 1, 3, nnd'4. 4It will be seen from the above description that the elastic-loops c c will all receive the weight of` the seat equally, and that'any weight upon the ends or in the centre of thc seat will act uniformly-upon ull-thespringsnt one time. The sent will not tilt on one sidein consequenceotn person sittmgpn' such side, as the seat. must rise and full in o horizontal p1nne. The

Having described my invention, what I claim asfnew,fnud desire to secure byLetters Pnt.ent,isl y 1. Supporting n seat upon two 'inclined 'boards B 'I B", whichlare jointed together at their inner ends and connected to the seat by y'moons' of springs c c, substalntinlly as'described.
